Part of Hermione wants to ask what Looms are, but when the Doctor implies they're part of how his people procreate, she backs off immediately, stifling a small blush. Really, that's just about the last thing she'd want to discuss with someone who looks as though he could be her grandfather, or at least her father's older brother. Best to just drop the subject before she finds herself unable to look him in the eye ever again.

Instead, she clears her throat and looks up, watching his more recent shot. "You're very good," she notes, a small hint of embarrassed strain still coloring her voice. "I'm impressed."
